256 Surgical Diseases and Surgery of the Dog 



Infected animals should not be allowed to mate. 



Papilloma of the Prepuce, Small growths, with or without 

 a pedicle containing melanotic deposits, the so-called pigmented 

 moles, are occasionally seen about the prepuce of black dogs. 



Treatment. Simple ablation with scissors serves to eradicate 

 these little blemishes. 



Sarcoma and Carcinoma of the Prepuce. Malignant neo- 

 plasm is of rare occurrence, and when it does exist is inoperable. 

 Petit and others have recorded instances. 



AMPUTATION. 



This operation is indicated when the organ is the seat of 

 malignant neoplasm or becomes gangrenous as a result of para- 

 phimosis or strangulation from other cause. The animal should 

 be anesthetised and hoppled in the dorsal position. The technic 

 is as follows: Draw the organ well out of the prepuce by means 

 of a tape tied round it, and apply a tourniquet above the proposed 

 line of section, which should be posterior to the os penis. Sever 

 the occluded portion of the organ with a scalpel. If section is 

 made through the bone a saw must be employed. Seize and ligate 

 all vessels with silk, expose the urethra and suture it to the free 

 extremity of the trunk with silk. Establish a prominent meatus 

 by incising the inferior wall of the extremity of the urethra for a 

 short distance in order to lessen the tendency towards subsequent 

 cicatrical stenosis. Remove the tourniquet and allow the stump to 

 slip back within the prepuce. For a few succeeding days irrigate 

 the parts with warm antiseptic solutions, and subsequently see that 

 the urethral orifice is maintained, by passage of the catheter if 

 necessary. Healing is usually complete in from ten to twenty days. 

 Should cicatricial stenosis of the urethra follow the best plan is to 

 establish a fistulous opening beneath the ischial arch by which the 

 animal may discharge its urine.
